Answer: social unrest

Explanation:

After the First World War, Europe’s working class went on a massive radicalization process. The political crisis following World War I, called "the red two years," or Biennio Rosso (1919-1920), revealed the weakness of the Italian states’. Within the process of radicalization, the Italian Socialist Party (PSI) started a dictatorship of the proletariat and was very successful, winning 32% of the votes in 1919 elections. Massive strikes broke up in several industries in Turin in 1919, and among agricultural laborers in North-central areas in Italy.
